I use to struggle to find the subjects of the verbs. I see two possibilities here:
“In order to forget their point of inferiority, we say they are a resilient companion and invent a fiction. And it also happens that sometimes the other simply decides that we are someone without virtue, even though we are normal people.”
“In order to forget their point of inferiority, they say they’re a resilient companion and invent a fiction. And it also happens that sometimes they arbitrarily decide that we are someone without virtue, even though we are normal people.”
In the first one, the subject acts like defending a friend who has inferiority complex (that’s the matter of the text).
In the second one, “自分たち” IS the person who suffers from inferiority complex.
To contextualize better, here’s the part of the article that precedes the one was translated:
This is a bit out of context, so take my interpretation with a grain of salt, but I would go with your second interpretation. The people who discriminate themselves believe that they are strong.
A very loose translation could look something like this:
“People who discriminate hide their own inferiority by fooling themselves in thinking they are strong. Sometimes other people decide that there’s something wrong with you, regardless of how normal you actually are.”
Just looking at the paragraph in question, I would say something like.
In order to forget our own weaknesses, we concoct a story in our heads that we are a strong group of friends. We also sometimes arbitrarily decide that the other side is weak, even though we’re just normal people ourselves.
I’m not sure to be quite honest. But it would be strange for me to think that this refers to someone’s perception of friends that discriminate others. The consecutive uses of 自分たち is kinda annoying, but if you see those as purely reflexive and self contained in their own group of words 自分たち1 = 強い仲間たどいう話を作る, and 自分たち2 = 正常の人間, then it makes sense to me that they designate something different.
I see. Thanks for the full text. Then I would stick with my interpretation, but add the idea of “group of friends” like Leebo translated. They fool themselves in thinking they’re a strong group of friends, that they’re strong people (together).
